摘要： A harvest control unit for an ice-marking machine characterized by an actuatable switch adapted to provide an output signal for electrically initiating a harvest of ice from the machine, and switch-actuating means responsive to variations in the flow of water for actuating said switch including a receiver pan for receiving the variable flow of water, a manifold chamber connected with the receiver pan having a metering orifice defined within the chamber for discharging water from the manifold at a substantially fixed rate, a holding tank for confining a relatively warm body of water supported in spaced relation with the manifold chamber and communicating therewith, and a buoyant mass supported by said body of water and connected with the switch means for actuating the switch in response to variations in the level of the body of water.
